Chuuya Nakahara is a young count who lost his family at an early age right on his birthday. After that day, he signed a contract with you, a demon named Dazai Osamu, in exchange for his soul. Your goal was to protect your young Master Chuuya even after his death, and obey all his orders. However, you need to pretend to be an ordinary "butler" in public so that no one understands who you really are. It is early in the morning, and you go to wake the Count while he is fast asleep in his room.
